Detailed Description

Output utilities for writing to file descriptors.

Functions that output characters, strings, and integers to a given file descriptor. These are useful in systems without standard output libraries.

This group includes:

• ft_putchar_fd
• ft_putstr_fd
• ft_putendl_fd
• ft_putnbr_fd

Function Documentation

ft_putchar_fd()

void ft_putchar_fd	(	char	c,
		int	fd
	)

#include <include/ft_output.h>

Writes a single character to a file descriptor.

This function writes the character c to the file specified by fd. It is primarily used for outputting a single character to a file or standard output.

Parameters

c	The character to write.
fd	The file descriptor to which the character will be written.

ft_putendl_fd()

void ft_putendl_fd	(	char *	s,
		int	fd
	)

#include <include/ft_output.h>

Writes a string followed by a newline to a file descriptor.

This function writes the string s followed by a newline character (\n) to the file descriptor fd. Commonly used to print lines of text.

Parameters

s	The string to write.
fd	The file descriptor to which the string and newline will be written.

ft_putnbr_fd()

void ft_putnbr_fd	(	int	n,
		int	fd
	)

#include <include/ft_output.h>

Writes an integer to a file descriptor.

Outputs the integer n as a string of digits to the given fd. Handles negative numbers and the special case of INT_MIN.

Parameters

n	The integer to write.
fd	The file descriptor to which the integer will be written.

ft_putstr_fd()

int ft_putstr_fd	(	char *	str,
		int	fd
	)

#include <include/ft_output.h>

Writes a string to a file descriptor.

This function writes the null-terminated string str to the file descriptor fd. It handles system interruptions (e.g., EINTR) and retries as needed until the full string is written or an unrecoverable error occurs.

Parameters

str	The string to write.
fd	The file descriptor to which the string will be written.

Returns

The total number of bytes written, or -1 on error.
